I think I figured it out. After reading a blog comment posted by Bill, I realized I epoxied the chainplate to the deck when I redid my deck. I also have the rig as tight as possible(45/46). I'm wondering why my cabinside doghouse has fine cracks along the fiberglass near the chain plate area on both sides. The stress from the rig is pulling the deck up. Looks like I have an excuse to buy the Fein Multimaster now. That would be the perfect attachment and tool for cutting close to the chainplate and bedding it like a normal boat owner. I'm then going to actually layup a 6" wide layer or two of glass tape at the seam where the cabin sides meet the deck. I'll run it the entire length to try and reinforce the area. Then paint it gray again. Thanks Bill. Even though you were unaware that you helped.
